A46b 3/00 U.S. Cl. -171 9 Claims ABSTRACTOF THE DISCLOSURE A broom construction with a tubular handle holder inthe central interior part of the broom, the holder having at least twoannular external rings and a plurality of radial pins; a hoop on theexterior of the broom and a soft laminar material covering the upper endof the broom which is pierced by metallic staples.

This invention relates to improvements in brooms. More particularly, theinvention is concerned with improvements in brooms of the type formed bya bunch of iliform elements gathered together at one end, at which theseelements are pressed together, besides being held down at or near theircentral part so as to give the whole a flat trapezoidal form and keepthis form stable during the whole life of the broom.

There are known many constructions of brooms of this type in which theliform elements, bunched together at one end, are tied, by means ofwire, around a nucleus which, prolongated, constitutes the handle of thebroom. In this type of broom said end is of circular section and theflat form of the broom is attained by means placed at the central part,so that the other end of the iiliform elements are spread out giving thewhole a substantially rectangular section two of which sides are muchlarger than the other two, which section is ideal for sweeping thewidest field with a given number of liliform elements. But all theseconstructions require very long iliform elements, together with normallylong ones, if the broom has to perform satisfactorily. That means ahigher cost than in constructions in which the very long element couldbe dispensed with and, on the other hand, compels the use of stuliingswhich, besides increasing the cost, frequently are cause of troubleafter the broom is used a long time.

It is also known to sew together, at mid-length, the bundles of liliformelements by means of organic yarns which are of relatively high cost andon the other hand of short durability which makes that, after a time,the initially trapezoidal bunch becomes subdivided in a plurality ofsmaller bunches, the number of which is practically the same as the oneof sewing loops produced by the sewing machine, which converts theoriginally continuous sweeping surface in a kind of rake that naturallyhas low sweeping efficiency, especially for small particles.

The novelty of this invention resides in that at the end of the broom,in which the filiform elements are bunched together, is placed a tubularhandle holder which has a plurality of external rings and a plurality ofradial fins against which said fliform element ends are pressed by meansof a hoop, and that the sewing, instead of organic yarn, is done withmetallic wire staples. This way said end 3,533,123 Patented Uct. 13,1970 pressing together of the iiliform elements with metallic stapleskeeps them unit with more Strength, during a longer time, since itpractically impedes the lateral and axial displacement of them and theformation of smaller bundles as well as the deformation of thetrapezoidal form of the broom.

The scope of this invention is defined as follows: lmprovements inbrooms of the type formed by a plurality of tiliform elements hunchedtogether at one end in which these elements are tied firmly against ahandle besides being tied together at or close to their central part soas to give the broom a substantially trapezoidal form, characterized bythe fact that at the central interior part of said end is placed atubular handle holder having at least two annular external rings, oneclose to its lower end and the other at its central part, as well as aplurality of radial ns; on the exterior of the liform elements beingplaced, in said zone, a hoop and the whole covered by a soft laminarmaterial having low elasticity which extends from said hoop upwards tothe superior end of said handle holder and downwards a certain distancewhere one of its faces is pierced by metallic staples the central partof which goes through the bunch of liliform elements at right angles tothem whereas the ends are bent back against the opposite face of saidcover of laminar material.

To explain in more detail this invention so that it can be bestunderstood in its construction and method of operation it will bedescribed in connection with the accompanying drawings in which:

FIG. l is a transversal section of the upper part of a bunch of tliformelements forming a broom, taken along its principal plane of symmetry.

FIG. 2 is a transversal section taken along line II--II of FIG. 1 of thesame broom; and

FIG. 3 is a transversal section taken along line III-III of said broom.

The handle of the broom (not shown) is inserted in the interior of tube1 which preferably is of plastic material and has its lower end halfclosed by means of ring 1 so as to avoid that said handle can penetratefurther and emerge below tube 1. The interior diameter of tube 1 issomewhat smaller than the exterior diameter of said handle so itsintroduction and extraction from tube 1 has to be accomplished using acertain amount of force thus guaranteeing its not getting out when notwanted to.

On its outer surface tube 1 has annular rings protruding, the moreimportant being the lowermost 2 and the central one 3. The other centralring 4 and the superior one 5 are optative, the later one having thepurpose of stopping the possible displacement of cover 8 upwards, andring 4 serving as a guide for the cutting machine that cuts the upperends of liliform elements 9 close to it. Between rings 2 and 3 areradial iins 6 (see FIG. 2) which preferably are parallel to each otherand the main symmetry plane of the broom. Surrounding rings 2 and 3, andiins 6, are the upper ends of yiiliform elements 9 guinea straw, vegetalfibres, plastic filaments, etc.) which are pressed together and againstsaid tube 1, by a hoop 7, in form of a steel band, whose extremes areiixed together by stapling, riveting, welding or the like.

Cover 8, in form of a hood, has an upper tubular part which fits overthe exterior surface of tube 1, below ring 5, although if the elasticityof cover 8 is very small, ring 5 has to be eliminated so as tofacilitate the placement of cover 8. The lower part of hood 8 is piercedby steel wire staples 10, the central part of which is normal to thelongitudinal axis of filiform elements 9 and whose free ends 10 are bentback upon the face of hood 8 opposite so the one through which saidstaples have been introduced. As can be seen in the drawings, betweenthe central part of staples 10 and the interior walls of hood 8 areformed rectangular spaces lled with iliform elements 9 which are thustightly pressed to the extent that those close to said interior wallsare practically incrustated in them.

The construction of a broom according to this invention is very easy andsimple as well as economic and fast. The extremes of normally longfiliform elements (the extra long one are not needed any more) arehunched together around the lower extreme of tube 1, between the rings 2and 3 and tied together by means of hoop 7. Then the upper ends are cut(using ring 4 as guide for the cutting knife) and cover 8 is placed andsewn on the zone indicated in FIG. 1 by means of wire staples 10. Thenthe lower end of liform elements 9 is cut to level them off. All thiscan be performed in a fraction of the time used in the manufacture ofthe known brooms and does not need specialized men as in the case in theknown brooms. Also there is no need for nails, wire, stuiiings, etc. Allthis makes this invention very important and a great advance upon theknown brooms and their manufacture.

Of course numerous modifications of details can be introduced in themethod and broom described. Hoop 7, for example, instead of being asimple band of steel can be made of several bands or of one or severalwires; the ins 6 could be more or less than the ones illustrated and ofgreater or smaller surface or inclination; the rings 2 to could be moreprotruding or of diferent section than illustrated; the cover 8 couldhave another form, etc., all being within the scope of the invention.
